Embodiments of the present invention provide a unique new approach to generating operating condition information used for assessing flow assurance and structural integrity. More specifically, apparatuses, systems and methods configured in accordance with embodiments of the present invention enable multiplexed arrangement of optical fiber for sensing of operating conditions within a structural member and utilize fiber optic sensors for enabling monitoring of operating condition information within one or more elongated tubular members. To this end, fiber optic sensors are strategically placed at a plurality of locations along a length of each elongated tubular member thereby allowing critical operating conditions such as strain, temperature and pressure of the elongated tubular member and/or a fluid therein to be monitored. A multiplexing unit is used for allowing selective configuration of individual lengths of optical fiber for creating one or more contiguous optical fiber structures.

A near-infrared sensor cover includes a cover body having transmissiveness to near-infrared rays. The cover body includes a base and a heater unit. The heater unit is arranged rearward of the base in a transmission direction of the near-infrared rays and includes a wire-like heating element. The heating element is configured to generate heat when energized. The base includes a rear portion that includes a rear surface of the base in the transmission direction. In the rear portion of the base, at least part of a section that is different from a section in which the heater unit is provided is formed by a reflection suppression structure including asperities. The asperities include a reflection suppression surface that is inclined relative to the transmission direction and reduces reflection of the near-infrared rays.

This application provides a single-photon detection apparatus that includes a phase-reversed reflection branch, a single-photon sensing device, a phase-unreversed reflection branch. An input signal is divided into a first and a second input signals, and the two input signals respectively arrive at the phase-reversed reflection branch and the single-photon sensing device. The phase-reversed reflection branch is configured to perform phase-reversed reflection processing on the first input signal, to obtain a phase-reversed signal. The single-photon sensing device is configured to send the second input signal to the phase-unreversed reflection branch, and is further configured to sense a photon, generate photon information, and output a first branch signal. The phase-unreversed reflection branch is configured to perform phase-unreversed reflection processing on the second input signal to obtain a second branch signal. The first branch signal is superimposed with the second branch signal, to obtain the photon information.

A mobile device can be used for detecting and communicating to a user at a location, sunlight exposure in relation to the user at the location. Sunlight intensity data at a location of a mobile device is determined, in response to receiving at the computer, GPS (Global Positioning System) data for the mobile device. The sunlight intensity data and the GPS data is analyzed to generate an estimate of sunlight exposure for a user using the mobile device at the location. A level of sunlight exposure for the user is determined, based on the estimate of sunlight exposure for the user, and using the mobile device, the level of sunlight exposure to the user is communicated to the user.
